This scatter plot visualizes the Iris dataset, mapping petal length and width to point positions, while color distinguishes the three species: setosa, versicolor, and virginica. The plot uses D3.js v6 with an SVG rendering, employing `d3.csv` to load the data, `d3.scaleLinear` for axes, and `d3.extent` to set the scales. Separately, sepal length and width are encoded into the marker's width and height, though the ellipse-like shapes still use `r` for a uniform radius. Axis labels are added via SVG text elements, and the visualization adapts to the window size.
